The thimble mounting hole 306, the first mounting hole 301 and the second mounting hole 302 are sequentially arranged from top to bottom along the vertical direction, and a top tightening portion 101 is arranged at the joint of the top sealing plate 1 and the thimble mounting hole 306. The thimble 2 is installed in the thimble installation hole 306, and the tightly-pushing part 101 of the top seal plate 1 can press the thimble 2 into the thimble installation hole 306.

The side of the carrier plate 3 is provided with a plurality of concave positioning portions 303 and a plurality of pressing portions 304 which are arranged at intervals, the pressing portions 304 are arranged corresponding to the first mounting holes 301, one side of each first mounting hole 301, which is close to the corresponding pressing portion 304, is provided with a positioning groove 305 communicated with the corresponding first mounting hole 301, the positioning grooves 305 are arranged at two ends of the corresponding first mounting hole 301, and a distance is reserved between the positioning grooves 305 and the corresponding first mounting hole 301, so that two ends of the PCB-2 are clamped on the positioning grooves 305. The side PCB pressing plate 4 is arranged on one side of the carrier plate 3, a plurality of pressing plate positioning convex parts 401 and pressing plate pressing convex parts 402 which are arranged at intervals are arranged on the side PCB pressing plate 4, the pressing plate positioning convex parts 401 are matched with the positioning parts 303 on the carrier plate 3, and the pressing plate pressing convex parts 402 are matched with the pressing parts 304 on the carrier plate 3; the bottom carrier plate 5 is provided with a third mounting hole 501 matched with the second mounting hole 302.
